4 1. Functions of the Skeleton The skeleton supports the body.The skeleton protects soft body parts.The skeleton produces blood cells.The skeleton stores minerals and fats.The skeleton (along with the muscles) permits flexible body movements.
5 2. Classification of bones Bones are classified according to their shape.Long (Longer then they are wide)Short (Cube shapes, about equal lengths and widths)Flat (Platelike and have a broad suface)Irregular (Varied shapes with many connections)Round (Circular shape)
6 2. Classification of bones Long Bones- Longer then they are wide)Longest bones providing support for the body giving it the rigidity (hardness) necessary to stand and move.
37 Formation of Bones Bone is comprised of: 26% minerals (mostly calcium phosphate and calcium carbonate)50% is water4% is fat20% is proteinBone requires adequate amounts of vitamins and minerals in the ration.
